SI DE-BAR WAGON.

SPECIFICATION forming part of Letters Patent No. 230,350, dated July 20,1880.

Application filed March 4,1879.

To all whom it may concern:

Be it known thatI, THOMPSON G. SEBRING, of Milford, in the county ofOakland and State of Michigan, have invented an Improvement inSide-BarlrVagons; and I do hereby declare that the following is a full,clear, andexact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,forming a part of this specification, and in which Figure 1 is aperspective view taken from the bottom. Fig. 2 is a side elevation. I

Like letters refer to like parts in each tigure.

The nature of my invention relates to new and useful improvements in theconstruction of lhatclass of vehicles usually denominated side-barwagons, and theinvention consists in the peculiar construction andcombination of the various parts, as shown in the drawings, and morefully hereinafter described.

In the drawings, A represents the body, provided with a centrallongitudinal bar, 15, mortised or dovetailed into the ends of the bottomframe.

0 represents the torsional springs by means of which the body andside-bars, D, are secured together. These springs are made of steel rodsof any desired size, and in the form shown, flattened at one end, as ata, bent at right angles to form the torsional part b of the spring, andthen again bent at right angles to form the lever c, so that the parts ac are on the same parallel vertical plane, and horizontally varyingabout twenty degrees, thus enabling me to make the leverc much longerthan it is ordinarily made, and by means of such additional length toobtain the proper height of the body.

The part a is rigidly secured longitudinally to the center bar, B, andthe part b to the sides of the frame of the body A, by means of the box(I, and the part c, at its outer end, is bent at right angles to itselfand pivotally secured to the arm 0, which is rigidly secured to therock-shaft E, which, in turn, is secured at each end in boxes km theside bars, D, which rest upon and are rigidly fastened to the bolstersor bars G. There are four of these springs and two rock-shafts, arrangedas shown in Fig. 1.

I am aware that thereare various constructions and arrangements oftorsional springs for vehicles, and I therefore do not broadly claimsuch springs; but

What I claim as my invention is--- In a side-bar wagon, the combination,with the body A, side bars, D, and bolsters G, of the four torsionalsprings O, secured at their ends a to the center bar, B, of the body,near the longitudinal centerot' such bar, then passing through boxes don the side frame of the body, and then bent outwardly toward thebolsters, where their outer ends are attachedto the side bars, D, by therock-shafts E, boxes h, and arms 0, all constructed and arrangedsubstantially as described and shown.
